soft black iron wire

The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.

The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.

Now the production of stainless steel blade barbed rope unless it is a specially customized model, under normal circumstances are the use of a knife length of 22mm mold production, that is, we usually say bto-22 type. It’s not necessarily the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the required length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.
